5 K-FLEX ACOUSTIC SOLUTIONS Whether at home, work or leisure, most of our time is spent inside buildings, so it is important that we feel comfortable. The optimum environment is created from a combination of the correct ambient temperature, humidity and lighting, access to necessary resources and suitable acoustic insulation. All these factors have to be taken into consideration when designing buildings, and will also have a direct bearing on the build cost and final project value. IK INSULATION GROUP 01 K-FLEX offers good value high performance acoustic solutions to meet the demands of today s buildings (both new-build and renovation projects) with high quality, excellent durability and optimum design, complying with the required regulations.

7 HOW SOUND IS PROPAGATED THROUGH BUILDINGS When a sound wave passing through the air meets a partition, some of the energy is reflected and the rest is absorbed. Part of the absorbed energy will spread within the partition, and the rest crosses through the partition and is transmitted to the other side. When looking at transmission of sound between two adjacent rooms, it is possible to identify different routes: direct through the partition, and indirect through the structure itself. In addition to this any sound caused by impact - such as furniture being moved, or people walking about - can spread within the building with the same mechanism as airborne noise. The difference is that the structure will vibrate when impacted by a solid object. ACOUSTIC INSULATION AND SOUND ABSORPTION Acoustic insulation is designed to minimize the transmission of sound between two areas, ensuring that the noise produced in one does not transmit to adjacent areas. In this way, a dividing wall between compartments and the surrounding facilities should ensure insulation against sound transmission. The other purpose of sound insulation is to reduce the reflection of sound from the structures of a room and reducing any acoustic reverberation. In all cases, materials for walls, ceilings and floors should be chosen for their sound absorbing performance and characteristics. EVALUATION INDEX The parameters defining the acoustic properties of a partition are measured in frequency bands of one third of an octave from 100 to 3150Hz. A wall is characterized by different values of the sound reduction index according to the frequency chosen. To facilitate the definition of the overall acoustic performance of a building component, with a single number, the evaluation index was introduced. This is calculated by using a procedure averaging the values to individual frequencies. (R = soundproofing capability by frequency, Rw = index of soundproofing capability, ΔL = attenuation of sound pressure level from footsteps by frequency, ΔLw = index of attenuation). The method for calculating this index is set out in UNI EN ISO (airborne noise) and UNI EN ISO (underfloor insulation).

13 K-FLEX FLOOR INSULATION Floor Insulation FLOATING FLOOR The floating floor is the most common technical solution for sound insulation in the building industry. To insulate a floor against the sound made by footsteps, a resilient material must be placed between the source of the noise and the building structure. The use of an elastic material installed under the floating screed, with certified performance of low dynamic stiffness value and capable of supporting the load of the screed, can reduce the transmission of vibration, increasing the value of ΔL w. When laying down a floating screed it is important to avoid contact between the screed and the perimetral structure. For this reason the resilient material installed on the floor should also be turned up against the walls to 5cm more than the final level of the floor.

36 K-FLEX CASE STUDIES CIVIL APPLICATION K-FONIK CIVIL APPLICATION Examples of K-FONIK products used to increase sound insulation performance in a building complex. The dividing wall was built from aerated concrete brickwork. The following acoustic insulation materials were used: > K-FLEX K-FONIK GK sheets high density rubber soundproofing > K-FLEX K-FONIK OPEN CELL 160 sheets - soundproofing open cell material made from FEF flakes compacted to the correct size and degree required to achieve the maximum performance over a wide frequency band. K-FONIK GK sheets (high density rubber 3mm thick) are applied to the existing masonry wall, made ready with a thin layer of tile adhesive using a serrated trowel. Application is easy and requires no special skills apart from attention to detail and accuracy, especially where there is a junction with adjacent materials. Next a lightweight metallic frame is constructed, attached only to the ceiling and floor. The profiles of the metal structure are detached and simultaneously sealed with strips of K-FONIK GK. Please note that the K-FONIK GK strips must be wider than the profiles in order to allow plasterboard to be attached, avoiding contact with the floor and ceiling. The resulting structure is not acoustically separated from the masonry wall. The vertical metal profiles are placed every 40cm, which makes the whole structure relatively rigid. The empty space between the light profiles of the metal structure is filled with sound absorption material, so as to increase the soundproofing properties and absorb a substantial portion of the acoustic energy. Plaster boards are applied to the structure. Note that there is an empty space between the plasterboard and ceiling/wall. This space (2mm) must be filled with acrylic silicone. The resulting structure features a significant increase in the performance of the acoustic insulation, thanks also to the specific installation technique, which enables the masonry wall to be effectively separated. The K-FONIK GK and K-FONIK 160 materials are integrated to improve the quality of the sound insulation. The consequent improvement in terms of sound insulation of the counter wall is equal to 8-10 decibels. COMPLETE CASE STUDY 36

37 K-FLEX CASE STUDIES CIVIL APPLICATION K-FONIK UPGRADING ACOUSTIC PERFORMANCES IN THE NEW SAP OFFICES. Procedure: K-FLEX proposed applying a layer of K-FONIK ST GK 072 to the existing structure in the ceiling, installed with a C profile inside the uprights and cross members together with a layer of K-FONIK GK (4 kg/m2) combined with a 60 mm layer of polyester fibre. The walls were insulated inside with polyester fibre panels, 60 mm thick with a density of 26 kg/m 3, placed between the dampening panels; K-FONIK GK 4kg/m 2 applied on the inside of the dampening panels; Laminated elastomeric K-FLEX ST GK 072 installed with a C profile inside the perimeter duct and the transoms; When the work was completed, the sound insulation index R on site was measured. SOUND INSULATION INDEX The partitions were intended to guarantee sound insulation with a minimum threshold of R w 40 db. Measurements of the apparent sound reduction index have been taken, according to procedure UNI EN ISO The sound pressure level was measured (db) for each partition evaluated. CONCLUSIONS R w insulated wall = 41 db The 40 db required by the customer was exceeded, and following our advice, all mobile office walls will be treated with K-FONIK products.
